Tier 0 (Boundless):

Characters who can affect objects which completely exceed the logical foundations of High 1-A, much like it exceeds the ones defining 1-A and below, meaning that all possible levels of High 1-A are exceeded, even an infinite or uncountably amount of such levels. This tier has no endpoint, and can be extended to any higher level just like the ones above.

Being "omnipotent" or any similar reasoning is not nearly enough to reach this tier on its own; however, such statements can be used as supporting evidence in conjunction with more substantial information.
